PARAMETER DESCRIPTION 144
5.10.1 DC injection brake
 When stopping the motor, apply DC voltage on motor to stop motor shaft from rotating, users can adjust the DC
brake time and braking torque.

DC brake
 After sending stop signal (please refer to chapter 4 for basic operation of starting and stopping the motor), output
frequency of inverter will gradually decrease. When the output frequency decreases to “DC brake operation
frequency (10-00(P.10)) ”, DC brake will start to operate.
 During DC braking, inverter will inject DC voltage into the motor coil to lock the motor rotor. This voltage is called
“DC brake operating voltage (10-02(P.12)) ”. The larger the 10-02(P.12) value, the greater the DC braking voltage,
and the better the braking ability. However, the braking current will not exceed inverter rated current.
 Operation of DC braking will maintain a period of time（10-01(P.11) value) to overcome the inertia from motor
rotation.

Note: 1. User must set appropriate values to get the best control characteristic.
2. If any one of 10-00(P.10), 10-01(P.11),10-02(P.12) is set to “0”, DC brake will not operate, when send stop
signal, motor may still rotate due to inertia.
